[texts]The effects of integrated care on professionals: a systematic review. (Volume 12) - Janse, B
This article is from International Journal of Integrated Care, volume 12.AbstractBackground and aim: Traditional care is increasingly being replaced by integrated care models, which often implies changes for health professionals involved. However, although literature on integrated care is abundant, the primary focus is rarely on professionals. Consequently, it is not clear if and how they are affected by integrated care interventions...

[texts]Relationship between perceptual learning in speech and statistical learning in younger and older adults. (Volume 8) - Neger, Thordis M.
This article is from Frontiers in Human Neuroscience, volume 8.AbstractWithin a few sentences, listeners learn to understand severely degraded speech such as noise-vocoded speech. However, individuals vary in the amount of such perceptual learning and it is unclear what underlies these differences. The present study investigates whether perceptual learning in speech relates to statistical learning, as sensitivity to probabilistic information may aid identification of relevant cues in novel speec...

[texts]On the universality of knot probability ratios - E. J. Janse van Rensburg
Let $p_n$ denote the number of self-avoiding polygons of length $n$ on a regular three-dimensional lattice, and let $p_n(K)$ be the number which have knot type $K$. The probability that a random polygon of length $n$ has knot type $K$ is $p_n(K)/p_n$ and is known to decay exponentially with length. Little is known rigorously about the asymptotics of $p_n(K)$, but there is substantial numerical evidence that $p_n(K)$ grows as $p_n(K) \simeq \, C_K \, \mu_\emptyset^n \, n^{\alpha-3+N_K}$, as $n \t...

[texts]BFACF-style algorithms for polygons in the body-centered and face-centered cubic lattices - E. J. Janse van Rensburg
In this paper the elementary moves of the BFACF-algorithm for lattice polygons are generalised to elementary moves of BFACF-style algorithms for lattice polygons in the body-centred (BCC) and face-centred (FCC) cubic lattices. We prove that the ergodicity classes of these new elementary moves coincide with the knot types of unrooted polygons in the BCC and FCC lattices and so expand a similar result for the cubic lattice...

[texts]The Compressibility of Minimal Lattice Knots - Esaias J Janse van Rensburg
The (isothermic) compressibility of lattice knots can be examined as a model of the effects of topology and geometry on the compressibility of ring polymers. In this paper, the compressibility of minimal length lattice knots in the simple cubic, face centered cubic and body centered cubic lattices are determined. Our results show that the compressibility is generally not monotonic, but in some cases increases with pressure...

[texts]Generalised Atmospheric Rosenbluth Methods (GARM) - A. Rechnitzer
We show that the classical Rosenbluth method for sampling self-avoiding walks can be extended to a general algorithm for sampling many families of objects, including self-avoiding polygons. The implementation relies on an elementary move which is a generalisation of kinetic growth; rather than only appending edges to the endpoint, edges may be inserted at any vertex providing the resulting objects still lie within the same family...

[texts]The pressure exerted by adsorbing directed lattice paths and staircase polygons - E. J. Janse van Rensburg
A directed path in the vicinity of a hard wall exerts pressure on the wall because of loss of entropy. The pressure at a particular point may be estimated by estimating the loss of entropy if the point is excluded from the path. In this paper we determine asymptotic expressions for the pressure on the X-axis in models of adsorbing directed paths in the first quadrant. Our models show that the pressure vanishes in the limit of long paths in the desorbed phase, but there is a non-zero pressure in ...

[texts]Minimal knotted polygons in cubic lattices - E. J. Janse van Rensburg
An implementation of BFACF-style algorithms on knotted polygons in the simple cubic, face centered cubic and body centered cubic lattice is used to estimate the statistics and writhe of minimal length knotted polygons in each of the lattices. Data are collected and analysed on minimal length knotted polygons, their entropy, and their lattice curvature and writhe.

[texts]cis-{2,6-Bis[(di-tert-butyl-phosphan-yl)meth-yl]cyclo-hexyl-?3P,C1,P?}chloridopal ladium(II). (Volume 68) - Olsson, Daniel
This article is from Acta Crystallographica Section E: Structure Reports Online, volume 68.AbstractThe PdII atom in the title compound, [Pd(C24H49P2)Cl], has a distorted square-planar CClP2 coordination geometry with the P,C,P′-tridentate ligand forming two five-membered metallacycles. The cyclo­hexane ring is aligned with the PdII coordination plane due to C—H activation in an equatorial position, giving a tri-equatorial conformation of the cyclo­hexyl ring.

[texts]Lattice Knots in a Slab - D. Gasumova
In this paper the number and lengths of minimal length lattice knots confined to slabs of width $L$, is determined. Our data on minimal length verify the results by Sharein et.al. (2011) for the similar problem, expect in a single case, where an improvement is found. From our data we construct two models of grafted knotted ring polymers squeezed between hard walls, or by an external force. In each model, we determine the entropic forces arising when the lattice polygon is squeezed by externally ...

[texts]Directed Paths in a Wedge - E J Janse van Rensburg
Directed paths have been used extensively in the scientific literature as a model of a linear polymer. Such paths models in particular the conformational entropy of a linear polymer and the effects it has on the free energy. These directed models are simplified versions of the self-avoiding walk, but they do nevertheless give insight into the phase behaviour of a polymer, and also serve as a tool to study the effects of conformational degrees of freedom in the behaviour of a linear polymer...

[texts]Partially directed paths in a wedge - E. J. Janse van Rensburg
The enumeration of lattice paths in wedges poses unique mathematical challenges. These models are not translationally invariant, and the absence of this symmetry complicates both the derivation of a functional recurrence for the generating function, and solving for it. In this paper we consider a model of partially directed walks from the origin in the square lattice confined to both a symmetric wedge defined by $Y = \pm pX$, and an asymmetric wedge defined by the lines $Y= pX$ and Y=0, where $p...

[texts]On trivial words in finitely presented groups - M. Elder
We propose a numerical method for studying the cogrowth of finitely presented groups. To validate our numerical results we compare them against the corresponding data from groups whose cogrowth series are known exactly. Further, we add to the set of such groups by finding the cogrowth series for Baumslag-Solitar groups $\mathrm{BS}(N,N) = $ and prove that their cogrowth rates are algebraic numbers.

Isolates obtained from diseased plants, however, were highly variable with regard to morphology and pathogenicity. The aim of the present study was thus to identify the Phomopsis species associated with die-back of...
